One UI 9 eligible devices include the Galaxy S23, S24, S25 and S26 series, the Galaxy Z Fold5 and Z Flip5 and every newer foldable, many recent Galaxy A phones, and the Galaxy Tab S9 and newer tablets. Samsung started the stable One UI 9 rollout (based on Android 17) on 16 September 2026 with the Galaxy S26 series, and by the end of October it had reached the S23, S24 and S25 families in several countries. Below are the dates Samsung has published, the device list from Samsung’s own pages, and what to do if your phone has not received the update yet.

What Is One UI 9?

One UI 9 is Samsung’s software for Galaxy phones and tablets, built on Android 17. It first shipped on the Galaxy Z Fold8 Ultra, Galaxy Z Fold8 and Galaxy Z Flip8, which launched with it in July 2026. Samsung then began rolling it out to older models as a free update.

In its rollout announcement, Samsung highlights these features:

  • Warranty and Care: a new Settings menu for warranty checks, self-diagnostics, repair estimates and service booking.
  • Now Nudge and editable Now Brief cards for context-aware suggestions.
  • My FanCam, which tracks one person in a video and reframes the clip around them.
  • Interpreter with a Thread View, and improved Document Scan for curved or folded pages.
  • Security Brief and Privacy Alerts, which flag apps that request background permissions they do not need.
  • Scam Detection expanding to more countries, including India, Japan and Canada.

Some of these features need a Samsung Account, and availability varies by country, language and model.

Which Galaxy Phones Will Not Get One UI 9?

The Galaxy S22 series is not on any Samsung One UI 9 list, and Android Authority reports that the whole S22 lineup is excluded.

For the Galaxy S23 series, One UI 9 is likely the last major Android upgrade. Samsung launched the S23 in February 2023 on Android 13 with a promise of four generations of OS upgrades, and Android 17 is the fourth. Samsung also promised five years of security updates, so security patches continue after One UI 9.

How to Check for and Install One UI 9

Before you start, back up your phone, connect to Wi-Fi and charge the battery. The download is large: reports put it at close to 4 GB on the Galaxy S25 series. You cannot use the phone, including for emergency calls, while the update installs.

  1. Open Settings.
  2. Tap Software update.
  3. Tap Download and install. On some models and carriers this button is called Check for updates.
  4. If One UI 9 is offered, let it download, then follow the on-screen prompts to install it. The phone restarts during the update.
  5. To confirm, go to Settings > About phone > Software information and check the One UI version.

You can also update from a Windows PC or Mac with Samsung’s Smart Switch app. Connect the phone with a USB cable, open Smart Switch, and select Update if it is offered. On Windows, install the Samsung USB driver first if the PC does not detect the phone.

Eligible but No Update Yet?

  • Staged rollout: Samsung releases One UI 9 country by country and carrier by carrier. In several cases former beta testers received the stable build first, and other users got it days or weeks later.
  • Carrier models: Samsung says schedules can vary by model, country and network operator, so a carrier version of your phone may get the update on a different day.
  • Check again later: open Settings > Software update every few days, and watch the Samsung Members app for notices about your model.
  • Avoid unknown firmware files: if you decide to install firmware manually, use only official firmware for your exact model number and region. Flashing the wrong file can leave the phone unable to boot.
